Yeah I would guess so!!! Blew a 1.5" section out of the gasket between my secondary and hot pipe. Man was the truck hot!!! Down 10psi as well. Get that fixed pronto and you'll notice a difference. I found a company while searching one day who sells a bunch of different fitting and gaskets. They make double thickness copper gaskets which are cool for sealing up imperfected flanges. I alway let the truck cool overnight and retorque all the fasteners, after the gasket change. Another tip, use the copper high temp(20?? Degree) neversieze on those fasteners.
As for your injectors, there slightly larger than mine. And I'm sure yours will like timing just as mine did. I have yet to hit the dyno again, but I'm hoping for better numbers there, as well as the track.
